Does it probably cause any problems to install different versions of Condor (for instance 6.8.5 and 7.0.4) in a processing pool? I am assuming that it is recommended working with the same version on all computers. However, it might be the case in our environment that we cannot update all computers at the same time.

IIRC 6.8 has some issues talking to 7.0 in some circumstances (the
important ones are that the collector/negotiator should probably be
the same. starter/startd should too (almost certainly you would do
this anyway) I haven't tried it myself, we are likely to try it soon
though. Those differences probably don't matter so much under clipped
ports like windows though.

Yep, works fine though you are probably best advertising the
bitness/architecture yourself. If you have jobs happy to run as WoW64
processes you don't want to restrict based on CPU_ISA.
You will also want to put in place an explicit (OpSys=="WINNT51" ||
OpSys=="WINNT52") etc etc or by default it will only run jobs on the
same windows version you submitted from.
